The Horsemen of Apocalypse are mutants who either willingly volunteer or are abducted and manipulated into the service of Apocalypse. They take their names from the biblical Horsemen Death, War, Famine, and Pestilence. They are almost always genetically modified by Apocalypse in order to enhance their abilities, or even grant them additional abilities. One such example was Archangel, who after losing his wings, was taken in by Apocalypse, who granted him metallic wings, with feathers that could be used as projectiles.
